larger than 6.84 cm SL was collected and most specimens larger than 5.0 cm SL were mature. An adjective.

duri punggung lunak (Keseluruhan (total)) : 10; Sirip dubur lunak: 11 - 12. Can be easily diagnosed from all lebiasinins, except Lebiasina melanoguttata, by the following characters: absence of the primary and secondary stripes, as well as the caudal
blotch; the presence of three longitudinal series of dark blotches at the base of the scales; the pair of foramina on the vomer through which the ramus palatinus of the facial nerve passes; the large laminar extrascapular bone in contact with the fifth infraorbital and overlaying the anterodorsal portion of the opercle; and the nearly equal caudal-fin lobes. Differs from Lebiasina melanoguttata in the presence of a dark blotch at the base of the middle dorsal-fin rays, the second infrapharyngobranchial being edentulous, the yellowish overall coloration of the body, the dark olive green eyes, and the dark blotches of longitudinal series 3 and 4 coalescing where scales of adjacent longitudinal series overlap (vs. dark blotch absent; second infrapharyngobranchial with conical teeth; the reddish overall color of body and eyes; and the dark blotches of longitudinal series not coalescing) (Ref. 91748).
Body shape (shape guide): elongated.
Facultative air-breathing in the genus (Ref. 126274)
